I thought it was incorrectly stated too, so checked the Argos and it's def oil-free! Didnt know they existed. Not sure what to make of this!

HOT!! Oil free just means environmentally better as far as I can tell, not sure on the running costs but reserved one anyway as the oil-filled heater that went through here the other day had such bad reviews!

Well, whatever it is you make, without the oil, you;d better use a non-stick frying pan! :whistling:

Oil filled one for 35 Quid coming up this Sunday:

If you only want a heater for occasional or emergency use, I prefer the quick warm-up of a fan heater:

Apparently oil free radiators heat up much more quickly.

Picked up this heater yesterday afternoon. And after getting over the initial 30 mins where it let's off a funny smell (this does disappear) I'm happy to say that this heater is amazing and a bargain for £30. It heats the room up very quickly and is more like a convection heater than an oil filled heater. It heats up super quick and cools down quickly. Great for heating a room when you've been out or have just woken up.

Does this have an adjustable thermostat? cant find much info online

How does an oil-free radiator stay heated?

I thought the oil kept the heat constant, because it doesnt cool down quickly.

There are two in north rd, durham. I just reserved one.

I bought this on Saturday, and it is roasting!!!! I love it! Heats the room up in no time. It has 2 settings, 1KW + 2 KW and also a thermo control. 2 on to start with, after 30 mins down to 1, and after about an hour, down to half the thermo...Roasting! Will cost you about 10p to run an hour on the 1 setting at full afaik.

I suspect it just has some other fluid instead of oil such as water and some anti-corrosive / anti-freeze mixture. If so, water has a very high specific heat capacity which means that it too will act as a "thermal mass" and iron out the highs and lows provided by the electric heater element.

Having a fluid is cheaper than having a solid metal heater and allows the energy to move around the heater by convection rather than just conduction. This means that you can have a smaller heater element at the bottom of the unit, which again reduces cost.
#19
There is some very misguided information in this thread. You cannot have a more efficient heater, it doesn't matter if it is oil filled or candy floss filled. The oil makes it safer as the heating elements should not be able to start a fire since they are encased in oil which should prevent overheating.

Just because the oil heats up and stays hot does not create more energy. It just means that in the first place more heat was being transferred to the oil than the room. You cannot create or destroy energy only convert it into different forms. All energy forms end up as heat so all heaters are exactly as efficient as one another.
#20
There is 1 left in the Staines branch.
#21
Just got one from Manchester Ancoats! Great find in the cold weather for work!!! Ta
#22
avoid these.

bought one in nov for £59.99 - broke after 3 weeks. I took it instore and exchanged for a new one and guess what? this morning its gone faulty yet again!

had 2 and both of them broke. Going to take this back and exchange for something else.

BTW challenge is in fact a argos brand, as the first time i didnt have a receipt to exchange but due to being there own product they did it without question.

They are good for the price etc but wont last you more than a few weeks!
#23
thanks for post, just reserved one in Melton Mowbray, still one left to reserve. cheers.:roll:
#24
I bought an 'oil filled' 2kw one from Aldi yesterday for £34.99 (till thurs 14/01/10).

Haven't tried it yet, but we want it for our kitchen which has no central heating, to come on in the morning for an hour before we get up to take the chill off the room. A virtually equivalent oil filled one (2.5kw) at B&Q costs £65.

For those interested in the Argos one in the Newcastle upon Tyne area, the stock levels are as follows...

Metro Centre - 1 left
Silverlink - 3 left
Northumberland street - OOS
Eldon Sq & Byker - Can be ordered for collection from Thur 14/01
#25
If your local stores OOS then they may have the 1.5 kw one for three quid more.
#26
I just rang my local store Gosport(Near Portsmouth) and reserved one. Shop assistant has confimed there is one more left. Anybody interested please ring and reserve ,here is the number to ring 02392512010. Please note its not showing stock on the website. Hope this helps for someone who is near Gosport or in Gosport.

Didnt think much could go wrong with these things but an extra £5 gives a 3 year warranty if people felt the need.

Glad someone has an education on here.

Anything wrong with one of these? Not that there's stock near me anyway.

No, and it's true to say heaters are equally efficient - but heaters dissipate heat in different ways.

I bought an oil filled radiator a few years ago (Dimplex Rio as pictured) I like the way it radiates heat.

#37
Don't these things convect instead of radiate? Or is that a whole other argument!
#38
They do both, but I suspect they dissipate most of their energy via convection rather than radiation. They would radiate more if they were matt black, but difficult to coordinate unless you are a Goth :)
